How does the archerfish get its food?

They swim directly beneath an insect, hovering under the prey, where the light refraction is the least. However, experimentation has shown that the Archerfish can hit prey at greater angles than a perpendicular angle without losing accuracy.

When an archerfish selects its prey, it focuses its eyes on it and sticks its snout just above the surface, squirting a jet of water at its victim. It does this using the narrow groove that is formed in the roof of its mouth. It presses its tongue against this groove to form a narrow channel, then contracts its gill covers to force a powerful jet of water through the channel. The resulting jet of water can be up to 2-5 m long, but their accuracy only allows them to shoot insects 1-1.5 m away. The fish can alter the power of the shot for prey of different sizes. If the first shot does not knock the victim into the water, the archerfish will keep trying.
